1.3 Specifications

The LP5867 is a high-performance LED matrix driver that integrates 6 constant current sinks with N (N = 7) switching MOSFETs supporting N × 6 LED dots, or N × 2 RGB LEDs. The LP5867 integrates 7 MOSFETs for up to 42 LED dots, or 14 RGB LEDs.

The LP5867 supports both analog dimming and PWM dimming methods. Each LED dot is adjustable with 256 steps for analog dimming. The integrated 8-bit, or 16-bit, configurable PWM generators allow smooth and audible-noise-free dimming control for PWM dimming. Each LED dot can be arbitrarily mapped into an 8-bit group PWM to achieve dimming control together.

The LP5867 device implements fully addressable SRAM to minimize data traffic. The ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5867 supports both LED open and short detection functions. 1MHz (maximum) I2C interfaces and 12MHz (maximum) SPI are both available in LP5867.
